Answer:
Step-by-step explanation:
Taking 25°C as the room temperature, there are only two elements that are remarkably liquid at room temperature; they are bromine, Br, (a nonmetal) and mercury, Hg, (a metal).
It is very surprisingly: the other 116 elements are either solid or gaseous at room temperature.
Nevertheless, a few degrees above 25° other elements will be liquid.
This is the case of:
- Caesium (Cs), whose melting point is 28.4°C
- Rubidium (Rb), whose melting point is 39°C
- Francium (Fr): whose melting point is 27°C
- Gallium (Ga): whose melting point is 30°C.
This information, of course, is found in tables which are available in internet and some textbooks.
